Answer: The two main factors that determine a planet's orbit are the mass of the planet and the mass of the object it is orbiting (such as a star)

Explanation: The gravitational force between these two objects causes the planet to follow an elliptical orbit around the object. The planet's velocity, or speed, also plays a role in its orbit, as it determines the shape of the orbit. The shape of the planet itself does not significantly affect its orbit. The planet's volume may have some effect on its orbit if the planet has a high density and therefore a strong gravitational pull, but it is not a primary factor.

Here's what I came up with :)

Answer:

The answer to this question is......C

Two or more than two atoms with different physical or chemical properties can not combine together to form an element. Therefore, Sr is the element which is most reactive. The correct option is option C.

Element generally consist of atoms or we can atoms combine to form element. Atoms of an element is always same, means all the properties of all atoms of one type of element is same.

On going down the group of periodic table, size increases due to increase in number of shells, easiness to eject one electron increases. Group 2 elements are the most reactive as it has only 2 electrons to loose. Sr is the element which is most reactive among all the given options.

Therefore, Sr is the element which is most reactive. The correct option is option C.

Earth spins around its axis, just as a top spins around its spindle. This spinning movement is called Earth's rotation. At the same time that the Earth spins on its axis, it also orbits, or revolves around the Sun. This movement is called revolution.

The second one since when light is aimed towards transparent glass it does not reflect back to you, and you cannot see it through the glass.

The correct image that shows how the light behaves as it passes from air and then through a piece of transparent glass is second one, because, the light ray will refract or bend when passing to other medium with a different density.

Refraction is the bending of light as it passes from one medium to another with a different density. The change in the speed of light as it moves from one medium to another causes the bending of the light, resulting in a change in its direction.

The amount of bending depends on the angle at which the light enters the new medium, as well as the difference in the refractive indices of the two media.

Refraction occurs when light passes through materials such as air, water, or glass, and it is responsible for a variety of optical phenomena, such as the way that lenses focus light to create images, the formation of rainbows, and the apparent bending of objects viewed through a glass of water.

Hence, the second image is correctly representing refraction.

All complex life on Earth is eukaryotic. All eukaryotic cells share a common ancestor that arose just once in four billion years of evolution. Prokaryotes show no tendency to evolve greater morphological complexity, despite their metabolic virtuosity. Here I argue that the eukaryotic cell originated in a unique prokaryotic endosymbiosis, a singular event that transformed the selection pressures acting on both host and endosymbiont.

The combination of massive bioenergetic expansion, release from genome-size constraints, and high mutation rate favored a protosexual cell cycle and the accumulation of eukaryotic traits. These factors explain the unique origin of eukaryotes, the absence of true evolutionary intermediates, and the evolution of sex in eukaryotes but not prokaryotes.

The example is most likely made from both metals and gemstones is necklace and the correct option is option 1.

Metals are natural compounds of earth’s crust, in which they are generally found in the form of metal ores, associated both with each other and with many other elements.

Metals are opaque, lustrous elements that are good conductors of heat and electricity. Most metals are malleable and ductile and are, in general, denser than the other elemental substances.

Usually, all the metals have a shiny appearance but these metals can also be polished to have a shiny appearance.

Therefore, The example is most likely made from both metals and gemstones is necklace and the correct option is option 1.

We observe when we watch kids blowing bubbles it is a property of density. Therefore, option A is correct.

The mass of a material per unit of volume is its density. Density is most frequently represented by the symbol, however Latin letter D may also be used. Mass divided by volume.

A liquid's density is a gauge of how heavy it is relative to the amount being measured. The liquid that weighs heavier is more dense if you weigh two liquids with similar volumes or quantities. A liquid that is less dense than water will float if it is gradually introduced to the water's surface.

By dividing a material's mass by its volume, the density of a substance may be estimated. The most common units for density are grams per milliliter, or g/mL, which is equivalent to grams per cubic centimeter.

Thus, option A is correct.
